The best smart watch for 2025 – CNET

We test smart watches in the real world, focusing on the main features of fitness tracking to the connection you will use every day. From the same hour, we check the general performance and response. Is there any delay when moving in the menus? Is the touch screen responding? Do applications work quickly?

Then we check if it contains all the functions you expect for the price. This may be everything starting from the process of playing music to cellular connection so that you can use monitoring away from your phone or a screen always. All smart watches need to call the phone, so we also evaluate the ease of navigation.

Durabness and design

Smart watches are something you wear on your body, so we evaluate the comfort of wearing them. We also know that everyone has a different wrist, so we try to see how it fits and feels a variety of people.

Then we look at how to stand up to wear with daily life. Some smart watches provide increased durability such as dust resistance, or water resistance suitable for activities such as diving in diving, and where possible, we will test it for ourselves.

Battery life

The battery life will vary depending on how you use a smart hour, so we test the battery life with some standard tests. We see the time it takes generally on one charge with features representing typical use, such as always showing and following sleeping and outdoor exercise with GPS.

Physical fitness accuracy and the accuracy of the health sensor

We test the accuracy of the smart watch sensors in two different ways. For example, the heart rate sensor is compared to readings taken from the chest belt, and the gold standard in tracking consumer heart rate is considered. We compare readings from the watch against the tape to settle the heart rate, and the heart rate during a variety of heart -based activities such as running or cycling. We check for the time it takes to call GPS when doing an outdoor exercise.

Other health sensors, such as a blood oxygen sensor, are compared with a pulse oximation scale wherever it is possible.
